I don't think the "broken windows" metaphor is very accurate for healthcare. A lot of healthcare spending is along a gradient of elective vs necessary and some continuum of quality of life improvements.
For instance, I could live with allergies, and all my ancestors just had to, but I have the option to spend money on allergy testing services, medicines, treatments, etc. People spend money on in-home professional care to get better treatment than going alone or relying on family, or spend money on care facilities as appropriate for their circumstances.
We have medicines for depression, anxiety, restless leg syndrome, ADHD, birth control, acne, weight loss, low testosterone, ED, poor sleep, eczema, psoriasis and a million other issues which people in the past, or people in developing countries today, simply had to live with that we have the privilege of having access to treatments for to improve our quality of life.
I know people who are affluent and outwardly "healthy" who spend thousands of dollars per year in the "healthcare" category that's entirely discretionary, but lets them keep looking young and playing tennis at 70 years old, or helps them juggle work, family and fitness at 40.
